To (615 107mm it may concern:

Be it known that we HARRY C. Rasmus- SEN and Josnrrr KELLNnn, both citizens of the United States, residing in the city of Brookiyn, county of Queens, State of New One of the objects of'our invention is to;

provide a device of this type which canbe manufactured at low cost :and 'whichcan be firmly and safely held and eificiently operated.

Another obyect of the invent-ion 1s to prov1de means at one endof the device to grasp the binding wire and hold same at the tw sted portion of the looped end where it will endure the most strain and tension, which method of holding the wire will obviate the necessity of renewinn and repairing the loop retaining; device as employed in present devices of. this character.

Another object of our invention is to provide means for holding the wire loop at. the end in an upright position, which will readily allow the insertion of the oth-er'end a I! J: a 1 of the wire 1or proper iastening and 3111107 tion.

Another object of our invention mit of the device being; firmly held in "place on thearticle to be bound. bothby means of the breast plate or handle at one. end and the flat edge of the other end. I y

Another object of our invention is to pro, vide driving means operable from the side by means of a specially devised driving mechanism, multiplying the il'pffllld power, and providing a compact, safe and strong; combination of handle and driving. means. This arrangement of operation. from the side enables the operator to hold the device by the handle or breast-plate by one hand, and simultaneously operate the device with the other hand.

Further objects of our invention will appear more fully hereinaft The invention consists substantially in the construction,

combination, location and relative arrangements of parts, all of which will be more fully set forth hereinafter, as shown in the accompanying drawings and finally pointed out in the appended claims. I

As shown inthe drawings, base 1. has mounted thereon, preferably; integral, the hearings or brackets Qand 3. Slot 4t isprovided to allow thecbloclrmemberfito slide back and forth on base 1. This block 5 has a stationary member 6 and movable menu her 7 secured thereto, both. of which are preferably provided with gripping teeth to.

graspone [endof the wire between them in the usual manner. Member .5 isalso secured to gear rack 8, which is slidahly mounted in bracket 3 :and groove 16, and is operable back and forthby the worm 9.

Revoluloly mounted in brackets 2 and is the shaft 10, having secured, thereon the worm Qand the bevel gear 11. Meshing;

with gear 11 is idrivingrgear 12, whichv mounted inbraclret 13, also preferably in tenral with base 1.

The handle 14, oraother, means of holding the apparatus, is provided at one end. At the opposite end of thedevice provided a slot 15, which is vnarrower at the bottom than at the top, havingslightly tapered walls... Slot 15 isalsoprovided with an inclined groove orpassage15, leading, up to it toprovidea non-cutting and smooth'lead. for the bindinguwire. The-purposes and advantages of. slot15 be. hereinafter more fullyexplained. p y y y I As shown in section Figure 1, the gear 12 ,isfirmly, held in place by the, set screw. 17 over which secured the (fa-p17, which is provided on the ins to fitoverthe set screw 17 and flush w th the surface of gear 12. Screws 18, 1.9 20 and 21 pfass t irough the cap 17 andintothegarlQ, and screws 19;an d ,also passthrough the handle 22, secnrin thegsame to cap. 16v r 12, thereb in the art. Pins 2?; and 721- 5' cure the 111611]? ber 6 to block Figure 2 shows the method in which the wire loop 25 is held in the slot or jaw 15 in a manner which will prevent breaking of the loop, at the same time holding it in an upright position through'which loop the other end of the wire may be readily and easily passed.

A description of the operation of this device is as follows, by which the improvements and benefits oi the device will readily be apparent to one skilled in the art:

The usual wire as employed in this character of work is passed around under the box to be wire-bound, and both ends brought to the'top. The apparatus herein described is then jammed underneath the looped end of the wire, which is pushed into the tapered slot or jaw 15. The opposite end of the wire is then led into the slot 15 and through the loop, which is automatically held in an upright 'osition, and inserted between the jaw mein ers 6 and 7. The handle of member 7 is then pushed down, firmly securing the free end of the wire. The apparatus is then placed at an angle on the box and can be fixedly held in position by the operator by means of the handle or breastplate 14, due to the driving mechanism being operable from the side, and the straight edge which rests on the box provides a rigid base on which pressure may be exerted-without danger to the operator in the event of the breaking or parting. of the wire. The side handle 22 is then operated, which moves the gear 12 therewith, revolving gear 11 and worm 9, which worm v9 moves'the gear rack S away from the loop 25, thereby tightening the binding wire. When the desired tautness of binding is obtained, the appara tus is turned over on its straight lower edge, the straight end of the wire thereby becoming bent or hooked over the loop, which is slipped out of slot 15 by the same oper ation; the device is then withdrawn by releasing the jaws 6 and 7, and the crossing or junction point of the wires is dealt a few blows with a hammer or the like. lhe re maining unused port-ion of the wire is then twisted around the bound wire, thereby making a rigid and tight junction of the loop and the straight end. 1

iVhile we have shown and described :1 specific structure embodying the principles of our invention, we wish it to be under stood that our invention in its broad scope as defined by the claims is not to be limited new and useful and of our own invention and desire to secure by Letters Patent is:

1. In a device of thecharacter described, a base member having means to receive and engage one end of a binding wire, a block member mounted to slide upon said base member and having clamping means to receive and retain the other end of the bindmg were, a slide rack connected to said block member, a worm gear engaging said rack, a shaft'on which said worm gear is mounted, bearings carried by said. base member in which said shaft is j'ournaled, and gearing for rotating said shaft.

2. In a device of the character described, a base member having a slot to receive and engage one end of a binding wire, a block member mounted to slide upon said base member, clamping means on said, block member for receiving and holding the other end of the binding wire, a slide rack connected to said block member, a worm gear engaging said rack, a shaft on which said worm gear is mounted, bearings carried by said base member in which-said shaft is journaled, a bevel gear mounted on said shaft, a cooperating bevel gear journaled tween, a block member, a projection on said block member for engaging said guiding slot, a clamping member and gear teeth projecting from the same face of said'block member on opposite sides of said projection, bearing brackets carried on said bascmemher, and means carried by said brackets for moving the block to tension the binding wire.
